Apple QuickTime Vulnerabilities

Original release date: May 12, 2006
Last revised: –
Source: US-CERT

Systems Affected

Apple QuickTime on systems running

 * Apple Mac OS X
 * Microsoft Windows

Overview

Apple QuickTime contains multiple vulnerabilities. Exploitation of
these vulnerabilities could allow a remote attacker to execute
arbitrary code or cause a denial-of-service condition.

I. Description

Apple QuickTime 7.1 resolves multiple vulnerabilities in the way
different types of image and media files are handled. An attacker
could exploit these vulnerabilities by convincing a user to access
a specially crafted image or media file with a vulnerable version
of QuickTime. Since QuickTime configures most web browsers to
handle QuickTime media files, an attacker could exploit these
vulnerabilities using a web page.

For more information, please refer to the Vulnerability Notes.

II. Impact

The impacts of these vulnerabilities could allow an remote,
unauthenticated attacker to execute arbitrary code or commands, and
cause a denial-of-service condition. For further information,
please see the Vulnerability Notes.

III. Solution

Upgrade

Upgrade to QuickTime 7.1. This and other updates for Mac OS X are
available via Apple Update.

Disable QuickTime in your web browser

An attacker may be able to exploit this vulnerability by persuading
a user to access a specially crafted file with a web
browser. Disabling QuickTime in your web browser will defend
against this attack vector. For more information, refer to the
Securing Your Web Browser document.
